Tony Mowbray has branded suggestions that £8m may be enough to take Aiden McGeady from Celtic to the Premier League as "ridiculous".

Speculation surrounding the Republic of Ireland winger refuses to go away, with Birmingham City retaining a strong interest. However, Celtic's manager has repeated that he values McGeady way beyond the sums which led to Craig Gordon and Alan Hutton swapping the Scottish Premier League for its English equivalent.

"The numbers you mention are ridiculously small numbers," Mowbray said when the £8m figure was put to him. "You say ridiculously high numbers, I say ridiculously small numbers. We're not interested in listening to bids for our players unless we're looking to move certain ones on."

He added: "This club is not in need of money. People leave because of their contractual situation or if I want them to leave, basically. There's no need for us to accept or listen to any bids we don't want. In terms of the player you mentioned, we're not interested in any bids. People are wasting their time phoning.

"There are precedents. Look at some of the players who have gone for whatever money if certain clubs come in. Look at the precedents Chelsea and Manchester City have set recently. Unfortunately for some teams, maybe like Birmingham City, the precedent has been set."

One player who has departed in recent days is Gary Caldwell. The defender, who has moved to Wigan Athletic, claimed Mowbray wanted to keep him in Glasgow but the board had other ideas with only five months of his contract remaining.

"It's too black and white to say that," said Mowbray, whose side host Falkirk today. "With any footballer there are contract negotiations that either conclude positively or lead to a parting of the ways. Gary's contract was running out and ultimately a deal was done. Anyone who leaves this football club, it's because the manager makes the decision that we've got to move things around. That's no secret. Since the day we've come in, players will come and players will go."

Allan McGregor is set to keep his place in goal for Rangers at Hamilton today amid allegations that he sexually assaulted a woman. Police are investigating the claim which McGregor has branded a "vile lie".

The Rangers manager Walter Smith said: "He will be involved in the team tomorrow and we will leave it at that."
